أَخْبَرَنَا إِسْحَاقُ ، حَدَّثَنَا عَبْدَةُ ، أَنْبَأَنَا عُبَيْدُ اللَّهِ ، عَنْ نَافِعٍ ، عَنْ ابْنِ عُمَرَ رَضِيَ اللهِ عَنْهُمَا، وَعَنْ الْقَاسِمِ ، عَنْ عَائِشَةَ قَالَتْ : كَانَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُؤَذِّنَانِ : بِلَالٌ وَابْنُ أُمِّ مَكْتُومٍ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِنَّبِلَالًا يُؤَذِّنُ بِلَيْلٍ، فَكُلُوا وَاشْرَبُوا حَتَّى تَسْمَعُوا أَذَانَ ابْنِ أُمِّ مَكْتُومٍ ".
فَقَالَ الْقَاسِمُ : وَمَا كَانَ بَيْنَهُمَا إِلَّا أَنْ يَنْزِلَ هَذَا، وَيَرْقَى هَذَا

Ishaq told us, Abdah told us, Ubayd Allah told us, on the authority of Nafi’, on the authority of Ibn Umar, may God be pleased with them both, and on the authority of Al-Qasim, on the authority of Aisha said: The Prophet, may God’s prayers and peace be upon him, had two muezzins: Bilal and Ibn Umm Maktoum, so the Messenger of God, may God’s prayers and peace be upon him, said: “There is good news.” He announces the call to prayer at night, so eat and drink until you hear the call to prayer of Ibn Umm Maktum.”
Al-Qasim said: There was nothing between them except that this man descend and this man ascend.
